SMOKING PIPE Filed April 1, 1930 INVENTOR M Mflu/ ATTORNEYS PatentedJano 3, 1933 "PATENT OFFICE NATHAN FRIEDMAN, OF YONKEBS, NEW YORK suoxmerm Application flied April 1, 1930. Serial No. 440,850.

My invention is directed to improvements in that class of smoking pipesin which a tortuous smoke channel is provided in the stem between thebowl and mouthpiece so that the smoke may be cooled and moisture removedtherefrom in its passage from the bowl to the mouthpiece.

My invention comprises a nine havin a bowl, a mouthpiece, and a stemremovably engaging the bowl and mouthpiece, and inner and outerreplaceable tubes located within the stem, the inner tube beingremovably supported by the mouthpiece and the outer tu e being removablysupported by the inner tube, W said tubes being preferably made ofabsorbent material, such, for instance, as paper.

A practical embodiment of my invention is represented in the accompanyindrawing, in which i Fig. 1 represents my improved smoking pipe inlongitudinal vertical section;

ig. 2 represents a horizontal section taken in the plane of the lineIIII of Fig.1,looking in the direction of the arrows;

Fig. 3 represents a transverse section taken in the plane of the lineIIIIII of Fig. 1, looking in the direction of thearrows, and

Fig. 4 represents a transversesection taken in the plane of the lineIVI'V of Fig. 1, looking in the direction of the arrows.

The pipe bowl is denoted by 1 and it is provided with a short lateralshank 2. A ferrule 3"is secured to the shank 2 and projects a shortdistance rearwardly therefrom. The shank is provided with the usual bore4.

The pipe stem 5 has its front end removably inserted into the ferrule3.. The mouthpiece 6 is provided with a reduced front end- 7 which isremovably inserted into the rear end of t pipe stem5. The bore 8 in themouthpiece 6 1s enlar ed at its front end for I removably receiving therear end of the inner tube 9 so that the inner tube is entirely suported by the mouthpiece. This inner tu 9 is open at both ends. An outertube 10 is supported by the inner tube 9. A closure is provided for thefront end of the outer tu which closure is herein shown "as a removablecap 11. p

The inner and outer tubes 9 and 10 are preferably made of absorbentmaterial and the cap 11 is preferably made of metal so that it maybeused with successive outer tubes.

When it is desired to replace the inner and outer tubes the mouthpiecemay be withdrawn from the stem, thereby withdrawing the inner and outertubes therefrom. The outer tube may then be slid off from the inner tubeand the inner tube may be withdrawn fromthe mouthpiece. A new inner tubemay then be inserted into the mouthpiece and a new outer tube may beinserted over the inner tube with the same closure 11 or anotherclosure, as may be desired. The I mouthpiece may then be re-engaged withthe stem for properly assembling the parts.

To ensure the free passage of the smoke from the pipe bowl to themouthpiece, the shank 2 of the bowl may be provided with a cut-awayportion 12 and the front of the reduced end of the mouthpiece may beprovided with a cut-away portion 13.

From the above description it will be seen that I have provided asmoking pipe in which the tubes which cause the smoke to pass in atortuous path from the pipe bowl to the mouthpiece, may be readilyremoved and replaced with a minimum expense.

It is evident that various changes maybe resorted to in theconstruction, form and ar- 80 rangement of the several parts withoutdeparting from the spirit and scope of my in vention; hence, I do notintend to be limited to the particular embodiment herein shown anddescribed, but

What I claim is 1. A smoking pipe comprising a bowl, a mouthpiece and astem removably engaging the bowl and mouthpiece, an inner absorbent tuberemovably engaging the mouthpiece, and an outer absorbent tube looselyand wholly supported by the inner'tube.

2. A smoking pipe comprisin a bowl, a mouthpiece and a stem removab yengaging the bowl and mouthpiece, an inner absorbent tube removablyengaging the mouthpiece, an outer absorbent tube loosely and whollsupported by the inner tube, and a front end closure for the outer tubecarried entirely thereby.

3. A smoking pipe comprising a bowl having a short shan a mouthpiece anda stem removably engaging the bowl shank and mouthpiece an innerabsorbent tube remov- Z 8 abl enga g the mouthpiece an outer ab sor enttub e loosely and wholly supported by the inner tube,'and a front endclosure for the outer tube carried entirel thereby, therear end of thebowl shank an the front 10 end of the mouthpiece having cut awayportions ensuring unobstructed passages beyolned the front and rear endsof the outer tu Q 1 4. A smoking pipe comprising a bowl having a shortshank and a ferrule secured thereto, a mouthpiece having a reduced frontend and a stem having one end inserted into fsaid ferrule and the otherend inserted over. the reduced front end of the mouthpiece, an in- 2oner absorbent tube removably engaging the mouthpiece, an outer absorbenttube loosely and wholly supported by the inner'tube, and 4 a front endclosure for the outer tube carried entirely thereby, the rear end of thebowl shank and the front end of the mouthpiece being shaped to ensureunobstructed passages 1belygnd the front and rear ends of'the outer Intestimony that I claim the foregoing as my invention l have signed myname this 31st day of arch, 1930.
